Answer
Exam answer
(d) char check(int x).
Explanation
A prototype has three parts: return type, name, parameter list. The method must RETURN a char, so it begins with char — which rules out (b) and (c). It must TAKE an integer, so the brackets must hold int x — which rules out (a). Only (d) satisfies both. Read such questions twice: once for what goes in, once for what comes out.
In words
char check(int x).
